A chemistry student needs 85.0g of acetic acid for an experiment. She has available 0.20kg of a 33.3% w/w solution of acetic acid in ethanol. Calculate the mass of solution the student should use. If there's not enough solution, press the "No solution" button. Be sure your answer has the correct number of significant digits.

Respuesta :

Answer: There is not enough solution.

Explanation:

We are given:

Mass of acetic acid needed = 85.0 gram

Mass of solution available = 0.20 kg = 200 g    (Conversion factor: 1 kg = 1000 g)

33.3 % w/w acetic acid solution

This means that 33.3 grams of acetic acid is present in 100 grams of solutio

Applying unitary method:

If 33.3 grams of acetic acid is present in 100 grams of solution

So, 85 grams of acetic acid will be present in = [tex]\frac{100}{33.3}\times 85=255.2g[/tex]

As, the given amount of solution is less than the calculated amount.

Hence, there is not enough solution.
